    • A mould and process for integrally forming from a selected material a helical shaped device which includes an axial member (33) integrally joined with a helical shaped flight member (41) is disclosed. The helical flight member (41) extends a selected radial distance from the axial member (33) and encloses up to 360 degrees of the axial member. The mould has a centre operating axis (26) and includes a first section (20A) which partially defines an elongated cavity portion (34A) which forms a portion of the axial member (33). The first section (20A) further defines a helical surface (36A) which is disposed coaxially around and along the centre axis (26) and extends a selected distance radially from the centre axis for an amount of rotation no greater than 360 degrees. This surface forms one of the front and back surfaces of the helical shaped flight member (41). In a similar manner, a second section (20B) is adapted for reciprocating movement along the centre axis (26) between an open and closed position with respect to section (20A). The second section (20B) also defines the elongated cavity portion (34B) and a helical shaped surface (36B) disposed around the cavity portion of section (20B). The helical shaped surface of section (20B) forms the other one of the front and back surfaces of the helical shaped flight member (41 such that when the two sections (20A) and (20B) are in the closed position, the helical surfaces of each section of the mould are parallel to and are maintained a selected distance apart. Thus, the two mould sections define a substantially enclosed cavity having an elongated axial portion and a helical shaped flight portion with a selected cross-section. It is this cavity when filled with a selected liquid material that may be cured such that it holds its shape that forms the helical shaped device. At least one of the two sections (20A) and (20B) define a gate or port (48) which extends from the outside of the mould to the internal cavity such that the selected liquid material may be transferred into the interior portion of the mould for forming the helical shaped device. In a preferred embodiment, there is also included a centre rod member (62) which is coaxial with the axial cavity (34A) and operates so that when withdrawn from the cavity it provides an aperture in the resulting axial member (33) of the helical shaped device. In addition, the mould and technique may be used to form helical shaped devices having more than one flight member so long as each flight member does not overlap another flight member.

    • The present invention provides an injection molding technique for embedding a volute flexible material (120) into reel (110) in order to produce a rotation assembly (100). At first, a volute component (120), a first mold (210), and a second mold (220) are provided. Next, the volute component is inserted into a corresponding volute fissure (228) of the second mold (220). In a following step, these two molds (210,220) are combined together in order to align a first end cavity (212) of the first mold (210) with a second cavity (222) of the second mold (220). Therefore, a reel component (110) of the rotation assembly (100) is blocked by injecting material into the space composed by the first end cavity and the second cavity through an injection hole (230). At last, the rotation assembly (100) is retrieved by decomposition of the first and second molds (210,220).
    • 本发明提供了用于以产生的旋转组件（100）中嵌入的蜗壳柔性材料（120）到卷轴（110）注模技术。 首先，在蜗壳部件（120）中，提供的第一模具（210）和第二模具（220）。 接着，蜗壳部件被插入到所述第二模具（220）的一个裂缝CORRESPONDING蜗壳（228）。 在一个步骤之后，论文两个模具（210,220），以便使第一模具（210）的第一端部腔（212）与所述第二模具（220）的第二腔（222）结合在一起。 因此，旋转组件（100）的一个卷轴组件（110）由将材料注射到通过注入孔（230）由第一端腔体和第二腔体构成的空间封锁。 最后，旋转组件（100）由所述第一和第二模具（210,220）的分解检索。
